Fertilizers suitable for RO water

[MateoinLosAngeles]

Some popular orchid fertilizers have their "tap" version and their "RO" one. Others, however, don't make any notes about whether they can be used with RO water without massively decreasing the pH.

Are there trusted brands of soluble fertilizers (let's skip MSU and K-Lite as we know those work) that can be used with RO water?

In my experience, Dyno-Gro acidifies the water a lot and I would assume it's a no-no. I'm not sure about Jack's or Peters.
